port, in the county of Lycoming and State ofv Pennsylvania, have invented a new and useful Reversing-Gear for Motor-Vehicles, dac.,

. of which the following is a specification.

The invention relates to improvements in reversing-gear for motor-.vehicles and the like.

The object of the present invention is to improve the construction of reversing-gear for motor-vehicles, and to provide a simple and comparatively inexpensive device capable of being readily adj usted to reverse a motor-Vehicle or other machine and adapted to enable the speed to be readily controlled, so that a vehicle maybe made to run either fast or slow without varying the speed of the drive or motor shaft.

A'further object. of the invention is to provide a simple andefcient device adapted to hold the parts at the proper adjustment and designed todis'pense with pawl-and-ratchet and similar devices which have to be thrown into and out of their locking position by hand, so that it will be only necessary for the operator to move the reversing-lever without manipulating the locking device.

The invention consists in the construction and novel combination and arrangement' of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in theclaims hereto appended. Y

In the drawings, Figure 1 is a reverse plan view of a motor-vehicle provided with a reversing-gear constructed in accordance' with this invention. Fig. 42 is a. transverse sectional view. Fig. 3 is a longitudinal sectional View. Fig. 4 is a horizontal sectional view on line 4 4 of Fig. 2. Fig. 5 is a detail Aperspective view of the transverse connectingbar. Fig. 6 isga detail perspective View of the `lower fend of the reversing-shaft, illustrating the construction of the cam.

Likenumerals of reference designate corresponding parts in all the figures ,of the drawings.

1 designates a transverse drive or motor shaft designed to be connected with the mo- .50 tor of a vehicle; but the reversing-gear may be employed on any other machine, and the said drive or motor shaft has aopairof friction-wheels 3 splinedv on it and yconnected by a hub or lsleeve 4 and adaptedV to engage alternately with an adjustable friction gear or pinion 5, whereby a longitudinal shaft 6, upon which the friction gear or pinion is mounted, may be driven in either direction. The friction gear or pinion 5 is provided on the interior ofits hub with a groove 8, which receives a .feather or spline 7, .extending longitudinally of the shaft 6, and the'said gear or pinion 5 is capable of movement longitudinally of the ,said shaft to arrange it at different distances from the center of the friction-wheels, whereby the speed of the longitudinal shaft may be `varied without changing that of the drive or motor shaft. VThe friction gear or pinion 5, is caused to mesh orl engage either of the friction-wheels 3 by shifting the latter transversely of the vehicle",and the frictionwheel is providedlwith agrooveV 9 to receive the feather or spline 10 of the motor-shaft.

The longitudinal shaft' is journaled in suitable bearings'll and12, the bearing 11 beingpreferably `provided with antifrictionrolls to relieve the parts of friction resulting from the lateral thrust incident to the frictional engagement of thewheels 3 and the gear or pinion 5. The .front end of the longitudinal shaft is connected by bevel-gears 13 and 14 with` a transverse shaft 15, journaled in suitableibearings and connected by sprocket-gearing 1G with the hind wheels 17 of the vehicle.`

The adjustable friction gear or pinion 5 is vprovided witha ball-bearing collar 1S, hav`- ing annular series of antifriction-balls arranged at its edges, and'it is connected with a yoke 2,0 of a lever 21, fulcrumedbetween its ends and extending outward from the longitudinal shaftto one side of the vehicle and connected atits outer 'end by a rod 22 witha suitable operating-lever, by means of which the friction gear or pinion 5 is adjusted.

One` of the friction-wheels 3 has a hub eX- tensio'n23, on which is mounted a ball-bearing collar 24, similar to that before described, and having annular series of antifrictionballs interposed between its edges and the IOO adjacent friction-wheel 3, and a xed collar of a connecting-bar 28, disposed transversely y of the vehicle and having its outer endbifurcated or forked and provided at the sides of the fork or bifurcation with similar loops formed by openings'` 29. Within the fork o'r bifurcation of the transverse connecting-bar springs 32, extending across the fork or bifurcation and supported by the openings of the slides thereof. The terminals of the springs are bent at right angles to form portions 33' for engaging the outer faces of the sides of the connecting-bar, and these springs engage the cam with sufficient force to lock the reversing-gear ineither position, thereby obviatifng the necessity of employing ratchet mechanism or analogous devices which have to be manipulated by hand independently of the reversing-shaft. The cam is provided at its lower end or face with an annular flange 84forming a disk to engage the lower faceof the forked portion of theconnecting-bar, and

the vadjacent facesof the connecting-bar and' the ldisk or flange are recessed or rabbeted to provide an interlocking connection for preventing the partsv from sliding on each other laterally of the connecting-bar and to form a guide for the latter in its longitudinal shifting movement.

tional bearing 35', and it is provided at its upper end vwith a crank or lever 36, which is connected by a rod 222L with suitable operatshaft it is only necessary to shift the crank or lever, andthe locking device will automaticall-y Vengage the cam and retain the friction gear or pinion in engagement with either of the friction-wheels.

The lever 2l, which has the yoke 2O at itsl inner end, is fulcrumed on ashort oscillating link v37, which permits the lever to move inward and outward to adjust itselfto the position of the friction gear or pinion.

The invention has thekfollowing advan` tages: The reversing-gear, which is simple and comparatively inexpensive in construction, is applicable to motor-vehicles and v-arious other machines. It 'is adapted to enable thesame to be quickly reversed, and it The locking dej adapted to be shifted to bring either of them in engagement with a friction gear or pinion,
